...AEROSPACE 4 hours Time it will take to fly from London to Sydney on a space plane being developed by Europe's EADS Astrium $308,200 Estimated cost per ticket aboard the proposed four-passenger craft. The 10,600-mile (17,000 km) journey currently takes more than 21 hours and costs about...
This spring three of the rugged ships stand out from the rest. Near Saturn, the Cassini orbiter, launched by the Jet Propulsion Laboratory, just executed a dramatic dive through an icy geyser that reaches 950 miles (1,530 km) into space from the Saturnian moon Enceladus, and there are plans to follow that up with even higher-risk maneuvers. In May NASA's Phoenix Lander will set down in Mars' arctic region in search of water ice. And later this month NASA and the European Space Agency will retire their Ulysses solar surveyor after a 17-year mission that...
...orbiter's plume dive was responsible for some of that shifting. Passing just 120 miles (190 km) above the surface of Enceladus, Cassini sampled an icy exhaust that researchers didn't even know existed until the spacecraft spotted it three years ago. NASA expects to release detailed composition information soon, but the ice hints at subsurface water and the attendant possibility of life. Seven more close-brush flybys are in the offing, including one high-wire plunge that will drop the spacecraft a scant 15 miles (24 km) above Enceladus' surface. Says JPL's Spilker: "We're going to taste...
...interstellar dust particles all the way from the sun to Earth, and in so doing helped map the planet's magnetic fields. The big surprise came when Ulysses stumbled on the tails of two comets and found that those feathery streams were more than 93 million miles (150 million km) in length. That's about the distance from the sun to Earth. "Totally unexpected," JPL project scientist Ed Smith says simply...
